29 Claims (01. 1076) The present invention relates to amethod of and apparatus for working a mass ofdough into a sheet. of substantially uniform thickness and. cutting a plurality of biscuits simultaneously from the sheet of dough in such a way that a minimum of scrap dough remainsafter the cutting operation. delivery of the individually cut biscuits simultaneously to baking pans which are later transported to the baking oven.

A primary object of the invention is to preliminarily work the dough into proper sheet form, and thereafter cut and pan the biscuits witha minimum of manual labor, thus materially increasing the commercial production of biscuits over known methods and consequently lowering their cost to the ultimate consumer.

The invention is especially adapted for the manufacture of butter biscuits which are formed from two or more layers of yeast dough between which is interposed a filmof butter or oleaginous material, and the invention-will be described in connection with the manufacture of biscuits from a dough sheet of this type. The invention, however, is adaptable also for the manufacture of biscuits from a single sheet or layer of dough.

The invention contemplates the breaking or rolling of a mass of dough into sheet form after which the sheet is spreadupon a work table and one-half of the upper surface of the sheet is coated with a film of butter orother oleaginous material. The dry portion of the sheet is then folded over the buttered half of the sheet, and the dough sheet thus constituted is thereafter delivered to a conveyor and moved rearwardly toward the dough-working or rolling mechanism. The foregoing steps are performed manually by a skilled attendant.

From this point on, the several steps to which the dough is subjected is performed mechanical- 1y by the machine under the control of an operator who takes a position adjacent the biscuitcutting mechanism. As the sheet approaches the working or rolling mechanism. it is caused to travel in a substantially horizontal direction between forming rolls which roll the dough to the desired thickness, after which it moves horizontally and in flat form to an intermediate conveyor. This conveyor, through associated mechanism, delivers a required portion of the dough sheet to the biscuit-cutting mechanism, which cuts simultaneously a plurality of individual biscuits from the dough sheet. Following the cutting of the biscuits, they are deposited in baking pans to be delivered later to the baking oven. Following the cutting of the biscuits, an uncut portion of the dough sheet is advanced to a position over the The invention also comprehends a including the working or rolling, conveying, cut-.

made to prevent this as the dough moves to and rests upon the cutting table. Provision is also made for the removal of; scrap dough from the cutting point.

From. the standpoint of hygiene, the dough is not touched by the hands following the delivery of the dough sheet to the proximity of the working or rolling mechanism, since all of the, steps,

ting and delivering to the pans, are occasioned by mechanical instrumentalities.

The above and additional features of the in vention will be hereinafter more fully described with reference to' the accompanying drawings, it

being understood that changes may be made without departing from the spirit of the invention.

Referring now to the drawings in which corresponding parts are identified by corresponding marks of reference;
